The Mark4 rack may need patching at the rear. For the v271 series the required patching is

VCs 1–3

IF 1 LO

VCs 4–8

IF 1 HI

Vs 9–14

n/a

The required patching seems to be shown in the procedure file generated below

When the appropriate receiver is on focus check the voltage levels of the VCs. You will have to have started the schedule (see below) or manually run the experiment setup procedure, e.g.:
→ > proc=v271ipa
→ > setup01

Check the experiment .snp file for the exact commands to use. The VCs need to be between 0.5 and 2.0 Volts. Leave the IF distributor on local and you can adjust the overall power by setting the two sets of attenuators on the lower left of this panel. Individual VCs can have a extra 10 dB of attenuation removed (default is in) by using the command (e.g.)
→ > vc06=340.00,16.00,ul,0,0
alternatively attenuation pads can be added (or remove) from the patch panel at the back.

Running schedules

Mk5 schedules are generated from the .vex files generated by SCHED. These are transferred (ftp) to pkvsi1, where the field system is run, in the directory /usr2/sched.

The utility drudg must be run to generate the run schedule for the fs in snap format (.snp) and the procedures file (.prc) which is saved in /usr2/proc.
To run drudg you on e.g. v271j.vex must type:
→ > drudg v271j.vex
then choose Pa for Parkes in the list of telescopes in the schedule.
